5 Impossible Flats

Zollikon is proud to discuss some flats recently designed to fit within a challenging but highly sustainable space. This development will bring a range of benefits:

  • enhance the neighbourhood by replacing a litter-strewn wasteland with a well thought-out and maintained scheme
  • replace unmanaged and even dangerous (dead) trees with an urban appropriate “living space” that includes retaining and managing wild trees, a new row of screening trees, a living wall, living roof and sustainable timber cladding materials
  • reduce a local flooding issue for at risk neighbours by enhanced monitoring of a riperian landowner who has a history of neglecting a waterway
  • eliminate any risk entirely for the scheme’s residents by building the ground floor and accesses above the flood tip-over point. (Unbelievably, this was not done in a large neighbouring scheme with dozens of flats just a decade ago!!!)
  • create a safer environment for neighbours using the “secure by design” principles of including windows overlooking public spaces, private ownership and usage. Granular statistics show crime is a problem for the general public in the immediate area to be enhanced by this much-needed Zollikon scheme
  • create much needed housing in a highly sustainable location, i.e. an area very well serviced by shops, schools, public transport, parks, medical care, work opportunities, etc.
  • create beautiful, space efficient homes with well thought-out layouts and features that people will be happy and proud to live in

Zollikon is very proud to have been involved in this scheme from the start – at which point every other person said this derelict, wasteland site was unbuildable – and to have then gone on to build and evidence the scheme’s merits, thereby securing the support of the local planning department despite all the “it’s impossible” nay-sayers.

A construction logistics plan, an extensive topograpical survey all the way to the local high street, uncovering historical records going back over 100 years, legal advice, pixel-level land registry agreement, 3D rendering, a highly original low impact build technique, graphs, photos, statistics, motion capture traffic surveys… The work was great, but the rewards far greater.

5 sets of residents will be glad that Zollikon creatively dreamed and diligently transformed the impossible into the possible, as they enjoy their beautiful new homes.

If you have a piece of land that you think might be buildable – even if “experts” have told you it is “impossible” – please do contact Zollikon for a fresh, intelligent appraisal.

Equally, if you would like to make an investment into land development, where returns of 2-20 times are achievable, Zollikon would love to speak with you about a possible partnership.

We are always happy to listen, look and think.

Zollikon – realising the possible.

Exciting times!

Zollikon has been hard at work for some time now on the new church development and final concept selection is about to take place from a short-list of two, before we prepare and submit the planning application. I would love to share details of the concepts with you – maybe later!

Elsewhere, old projects are now being built and yesterday a delayed planning decision on a listed building from early in the year was successful after some to-ing and fro-ing with the Heritage Officer – the client now has all he sought including a new granny annex, kitchen/dining/family room, study, walk-through library, boot room, dressing room, additional en suite, double-height glazed entry, lowered and reinstated parapet roofs, solar panels, landscaped approach, additional parking and other internal layout and fenestration improvements. It really is very satisfying to play a small part in helping a lovely young family achieve their dream home in a stunning location whilst also securing sustainable investment into a fantastic old heritage building.

Approaches continue from repeat clients and new enquirers who have heard of Zollikon by word-of-mouth, and there are now several very exciting avenues on the horizon for next year. Whichever path/s opens up, more in-house development work or some interesting partnership possibilities with great people who have proven track records in their specialist fields, 2020 is already looking good.

Of course, some of the most satisfying work is on individual homes and improvements for families, as mentioned above, so I very much intend to keep going with this fun and rewarding work too. I hope the feeling is mutual and very generous, unsought bonuses recently from two wonderful clients suggest something is right!

There is plenty more learning, hard work and mutual success waiting…

New detached house – Zollikon wins another appeal

From the very start I thought the application was a 50/50 case and indeed we did fail at the first attempt, when the Local Planning Authority (aka ‘the council’) rejected the application. The case had its definite merits and issues, but no neighbours had objected and on balance the clients and I agreed that the application ought to be given another chance – the application simply ‘felt right’.

So we pulled out all the stops for an appeal. We gathered further evidence to counter the LPA’s reasons for refusal, including going through the LPA’s own adopted policies with a fine tooth-comb. This detailed process unearthed some useful ammunition which we presented using all the skills learned from previous experience as a journalist, photographer, editor, Chartered Institute of Marketing post-grad, PLC communications manager, etc.

The rain started falling exactly as the Appeal Inspector arrived for his visit to view the proposed building plot. He declined a warming coffee and seemed tentative when we offered him a wet ladder to climb up (to see the neighbour’s garden for comparison purposes) despite my assuring him I had just secured and tested it. He survived. I also guided him around some soaked decking in case it was slippery. No slapstick mishaps please! Several minutes after he had left, we saw him outside in the street, still musing the situation. We struggled to interpret his body language – if only we could read his thoughts – perhaps he thought it was a 50/50 case too?

One morning a few weeks later, I excitedly phoned the clients to let them know the happy news of our win – clean forgetting that they were away in America. I have never heard someone more forgiving after being woken up at 5am!

Builders are now being engaged and the clients are looking forward to enjoying their new house.

Zollikon wins new church commission

It’s a great thing to see a new church being built in 21st century Britain. Particularly a decent sized one for several hundred people, in the beautiful grounds of a large Victorian gothic mansion which is celebrating its 150th birthday.

Zollikon is delighted and privileged to assist with the design, obtaining planning permission and build of this fantastic new worship, community and conference space for a thriving, exciting church.

Though in the early stages of involvement, there are already some fantastic, innovative ideas around the architecture and uses currently being researched and modelled, including one that would be a genuinely exciting UK first. The project’s previous scoping architects did excellent work to take several masterplans though 2 pre-application cycles with the Local Planning Authority, with Zollikon arriving to oversee the second pre-app LPA meeting and lead the project into its next phases.

As a Christian, it has been a real joy to join the current church in Sunday morning worship and to work with and chat through the week, to really try and understand the church’s vision and values. Highlights? The thumping dance music that crescendos as the service is about to begin, followed by the thumping sermon exhorting us to step out and make a difference, the mid-service coffee break, the passionate conversations I have had with members about their visions for the new church building, the servant hearts I’ve met who work hard to make the existing facilities work for the church and community, climbing up the narrow, winding steps of the gothic tower to survey the surrounding views of town and country… lots of highlights!

From really knowing and understanding the existing church community, the wider communities (including residential, educational and business), current stakeholders and tenants, the huge mansion, outbuildings and grounds – and holding these factors within the contexts of current technologies, budgets, multiple visions and more – Zollikon is synthesising the historic, the current and the sustainable future. And THAT, is indeed a privilege.

More to follow…

Flat roofed, full width, front dormer – win

These are often an unthinkable offence against design and planning policy in many planning departments. Many don’t even like them on the rear of houses but are powerless to stop them under GPDO / PDR legislation (developing an example of which has been keeping the grey cells busy this morning).

But the front, full width, flat dormer is not impossible, as Zollikon has just proved by achieving planning permission for exactly this – at the first attempt. A little more attention to the Design Statement than usual developed the case by close reference to the existing house design and an analysis of neighbouring architecture and recent planning decisions in the area to show how the proposal would actually result in a better outcome than might be the case if simply unthinkingly following rules and guidelines without any flexibility.

Thankfully, the LPA (Local Planning Authority) agreed that the proposal would ‘ameliorate the grain of the local vernacular’. Exactly!

Government raises planning application fees by 20%

Twenty per cent. That’s a fair bit, particularly when some planning departments who claim to be tremendously overworked seem to spend an awful lot of time and money fighting doomed appeals following wrong refusals. It’s the latest in a long line of rising taxes around planning and property, e.g. many planning departments have already increased their income in recent years by bringing in hefty charges for pre-application advice (in my experience the money is normally more wisely spent on an expert planning consultant who is freer to give a more balanced and creative opinion).

The increase has just been announced for 17th January, so you have a full FIVE DAYS to get your application in!

Although some will see this as payment for a service, I see it as yet another tax-hike because developers are enhancing a vital community asset for this and future generations – the built environment – at their own private cost. If the collective community wants to police this in ever-finer detail with more and more red tape, then it should collectively pay for this.

It could be argued that this size of increase is unlikely to deter any homeowner from attempting to improve their greatest asset, nor any land-owner from trying to add some zeros to the value of their land. Governments have always sought to increase tax revenues. There’s a lot of money in obtaining planning permission and this move is part of a trend of tapping into what is seen as an easy target, in order to finance an ever-growing army of those in public pay.

  • Joint venture, finance, plans, building regulations, build management consultancy for new property developers.

  • Plans, planning permission, building regulations, build checking for rear extension covering entire back garden in conservation area (subsequently recommended for and achieved planning for two storey extension in same conservation area, subsequently recommended for third extension in same conservation area…)

  • Design, planning and building regs for eighth customer in the same road completed! – all word of mouth recommendations.

  • Extensive project to combine two flats into one house, convert loft and add double side dormers and lower ground floor extension, remodelling to include: extra bedroom, extra en suite, extra toilet, extra utility room, 2 new offices, reworked bedroom, new bathroom, new open plan kitchen-diner-family room, 3 new staircases. All achieved within permitted development rights.

  • Extensive remodelling and extension to house forming one wing end of Grade II listed 18th century stately home in AONB, following Zollikon success on the other wing’s sister house.

  • Plot-finding, site acquisition, topographical survey, plans and planning application for 5 new flats on vacant urban brownfield site.



Perhaps your project contains elements similar to one or more of the above examples? Perhaps you have a new challenge for us – we love overcoming challenges! Zollikon has a lot of experience, skills and hunger to succeed for our clients. We look forward to helping you.

Loft Stairs

There are several great advantages to converting a loft compared with a ground floor extension:

  • no costly new foundations needed (subject to checking)
  • no new roof needed
  • no wasted garden space
  • upstairs bedroom/s
  • loft bathrooms/en suites can make good use of eaves
  • upgrading roof insulation benefits the whole house
  • generous planning PDRs can reduce planning costs and risks

So, lots of good reasons to consider a loft. These pluses need weighing against issues such as the need to consider fire safety, structural reinforcement and noise transmission, but so long as the basic height needed is there, a loft is a definite possibility.

One issue that does need consideration at an early stage is access – stairs.

Issues include:

  • Stairs and access to them, will cost space on the first floor
  • Placing loft stairs over existing stairs can be an efficient use of space
  • Stairs typically need to arrive in a high point of the roof to provide enough headroom
  • Building regulations stipulate a maximum stair pitch of 42 degrees
  • Each tread must have a minimum of 2 metres clear height above, except loft stairs, which may have a centre-line height of 1.9m with a lower edge of 1.8m to allow for a sloped roof above
  • Loft staircase headroom can be helped by Velux/roof lites and dormers
  • There are also minimums for stair landings and rules governing door openings near stairs
  • If the stairs create accommodation on a third floor, enhanced fire safety requirements and protected route escape rules can be met using a whole range of tools (e.g. linked smoke alarms, heat detectors, fire doors, intumescent products, fire boards, fire curtains and sprinkler systems)
  • Carpeted loft stairs will be quieter for nearby bedrooms
  • Winds and low ceilings will impact on moving larger furniture
  • For minor breaches, building inspectors (local authority building control officers or approved independent inspectors) have some discretion to decide what they consider to be a safe staircase
  • There is no rule governing the minimum width of private staircases
  • Risers and treads must be consistent – adding or removing height to the bottom step to make up for an error is not OK!
  • Spiral staircases and space saver (alternating treads) stairs can be an option.
  • If buying a second hand staircase, please consider/remember (or Google!) the 100mm sphere safety rule.

And so on.

Of course, you do not need to learn all of the above; Zollikon is here to take the technical load off your shoulders and assist as you specify your priority and design preferences.

Zollikon uses 3D CAD software which is a huge benefit when dealing with tight spaces, minimum heights, rising steps and sloped ceilings. We can add thickness to loft floors and ceilings to show the impact of reinforcing and insulating work needed in loft conversions. From your point of view, you will get to see your staircase, floor, walls, ceilings in 3D from any angle you like. We can even populate the model with people of your height to help understand the dimensions.

The sort of experience, expertise and software that Zollikon offers will go a long way to making a complex subject user-friendly for you. Loft stairs – tick.

New Year, New Start

Welcome to another year! 2018 holds much promise as Zollikon Architecture relaunches following a build sabbatical – an immensely tough and rewarding challenge.

Early this year we plan on giving the website a makeover and producing some printed marketing materials designed to bring useful information and benefits to interested clients. We are also looking at moving into a new office that enjoys a view over a golf course just 20 feet away through it’s panoramic glass wall. OK, OK so it’s a converted double garage but the location and aspect are truly inspirational!

Despite some incredibly long hours last year, somehow we also managed to find time to obtain and apply for planning for some more new flats on a brownfield site of our own. It’s always exciting to win planning applications, but when it is your own things are more personal and intense. Several clients have commented on how they appreciate the extra mile that Zollikon goes – which is largely thanks to having personal experience of the journey that clients go through. We should know more soon and whatever happens it will make a great case study before too long…

In the past year of ‘busman’s sabbatical’, Zollikon has only worked for two clients – the first project was for some friends with a growing family who needed a lower ground floor rear extension, two side-dormer extensions and complete remodelling to include: two new offices, new kitchen/diner, new bathroom, extra bedroom, extra en-suite, 2 new WCs, new utility room, three new staircases linking 4 storeys… all in a house at one time gutted by fire and all achieved under permitted development rights.

The other project is one wing-end of an 18th century grade 2 listed stately home set in glorious AONB woodland and overlooking a gently sloping garden, with ha-ha, paddock and fishing lake beyond. The clients have grand designs to extend and refurbish to very high standards and although busy, persuaded Zollikon to take on the project on the basis that we had previously succeeded with the other wing of the same house in what some hold to be a tricky planning district.

And so to 2018. We look forward to exciting new projects and challenges, to happy clients and a job well done. Carpe diem!

Zollikon Architecture flats launched to market

When we bought our small terraced home in 2007, little did we know that 10 years later we would have successfully extended and converted it into 4 flats.

It has been a long, transformative, arduous, educational, profitable and ultimately uplifting process…

The site always had potential but it took some creative design to enable 4 viable flats on a very tight site. There was also quite a battle with the local planning authority who were fantastically unhelpful – and wrong! as proved when they were forced to accept the obvious merits of our case by the Planning Inspectorate at appeal.

Then there was the credit crunch mess of cowboy banks gambling too much (of taxpayers’ money) and then too little (to protect their bonuses?!). I will never forget one large lender withdrawing from the market telling me they were unwilling to lend for our flats in Surrey as flats were risky because “there are lots of unsold flats in central Manchester”! Words fail.

Then a widely recommended builder promptly went bust days before starting, leaving us with no option but to self-build to beat a fast-looming planning deadline. Later, the water company managed to dig up the footpath 7 times before getting it right and we had to synthesise and redraw 6 contradictory electrical supply technical plans from the statutory supplier into one definitive drawing which they immediately approved. So, not always easy.

On the positive side, it has brought a huge breadth and depth of hands-on knowledge, a tremendous feeling of satisfaction, a healthy profit and a fantastic contribution to the community and its housing stock within 10 yards of a busy London commuter railway station. Within days of launch an airline pilot and young couple wanted to move in, with many more viewings being booked. Neighbours and a local housebuilder have stopped by to congratulate and thank us on a job well done to improve the area. The first building directly opposite anyone leaving the railway station is now not a dilapidated eyesore but a bright, transformed development to welcome and lift the spirits of travellers.

I am glad now to have more time to spend on Zollikon Architecture again – and with much enhanced knowledge. Despite, or perhaps because of, the countless obstacles met and overcome through sheer bloody-minded hard work over years, the flats project will remain a source of pride (and hopefully income) for many years to come.

An artist selling inspirational artwork in Covent Garden recently reminded me of some powerful words by President Theodore Roosevelt:


“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

It still strikes a chord as I read it now. Thankfully, we met every defeat, and every armchair critic, with a victory.
