Waverley Borough Council have granted a Lawful Development Certificate for a two storey rear extension for a client in Farnham. The client approached us after two previous planning applications for a two storey rear extension by another architect were refused. The client had reluctantly decided that they could no longer pursue the two storey option and asked us initially to look at a single storey design only – when we pointed out what could be acheived under Permitted Development Rights, avoiding the need for a full planning application and the possibility of a third refusal, they were amazed and instructed us to proceed accordingly.

The key to all things is a full understanding of the subtleties of both the local planning policies and the national Permitted Development Rights.

The three new contemporary eco-homes designed for Econvery Developments Ltd in Church Crookham, Hampshire are now all completed and occupied. The houses incoporate many eco-friendly technologies and features including wood-chip boilers, photovoltaic panels as well as solar thermal heating, triple glazing and green roof to the rear.

The pair of new semi-detached houses constructed for Gold Property Developments in Buxted, Uckfield, East Sussex have now been completed. For more details see the Projects page. The client came to BWP Architects with planning permission in place and we were commissioned to prepare the construction drawings only.

We also prepared a series of alternative designs, one of which is shown below, to improve the elevational treatment but the client wished to proceed with the current design in order to minimise any delays to the construction period.

We have recently prepared a loft extension scheme for a semi-detached property in Leadhall Avenue, Harrogate.

The proposals were developed to comply with Permitted Development Guidelines and we have obtained a Lawful Development Certificate from Harrogate Borough Council in advance of the work commencing

The Permitted Development Route route ensured that our client can get the extra space they require without the uncertainty and expense of a full Planning Application.

Regular followers of our Twitter feed (@bwp_architects) and our Blog (www.bwparchitects.com/blog) will know that in November 2011 the three partners all decided to take part in ‘Movember’ – a world-wide charity event which sees men growing moustaches in aid of Prostate and Testicular Cancer charities.

Well, the final money is now in and we’re delighted to report that between us we managed to raise a total of £935…. not too shabby for doing very little (apart from itching alot and listening to complaints from the children….)!

Following a planning refusal earlier this year for a scheme prepared by another practice we were contacted last month by a client looking for a new design and approach.

The client, disheartened by the outright refusal of the earlier scheme, had decided to drop their ideas for a two storey rear extension to give them a larger ground floor plan but alos a much needed additional bedroom, larger family bathroom and first floor study. Instead they simply wanted us to look at a design for a single storey rear extension.

However, using our detailed knowledge of the Technical Guidance on Permitted Development Rights, we have now completed the designs for a two storey rear extension that answers everything that the client wished for in their initial briefing – the extra bedroom, larger family bathroom and first floor study as well as a ground floor music room, new large kitchen / family room and separate utility room.

All of this has been created using their existing Permitted Development Rights thereby circumventing the need for a full planning permission application and avoiding the possibility of a refusal or objection from the planners.

It always pays to take proper advice from suitably qualified Architects who know the planning system properly – you never know what you can acheive unless you ask!

The detailed application for 276 homes for Persimmon Homes Yorkshire has finally been approved. The proposals were developed with the client, FDA Landscape and Haigh Huddleston Associates following extensive pre-application discussions with Doncaster Planning.  The planning officer praised the designs stating that ‘the scheme will deliver a good quality housing environment and vibrant new development that includes a mixture of accommodation which will make a positive contribution to the area’.

East Hampshire District Council yesterday granted planning permission for our application for a new detached house of 4,200sqft to replace a small bungalow on a large tree-lined site in Liss, Hampshire.

The project is for developer Peter Hawkes and this is our third project working with Peter.

In the second of our series on technical advice from specialist suppliers, Effi Wolff of www.balconette.co.uk talks about the design of privacy screens:

Many times together with requests for glass railings and balustrades there are requests by customers for what is known as a “Privacy screen”.

“Privacy screens” are what is often requested by local authorities. This is stipulated by them if your terrace, balcony or part of them only overlooks a neighbour’s property. It is requested so that your use of this balcony area does not invade or compromise their privacy.

Privacy screens are usually requested to be 1.8m high and use a glass that cannot be seen through – i.e. an opaque glass.

The subject of privacy screens and their height requires extra consideration for wind loadings and the subject of wind loading is not a simple calculation as there are many variables that need to be considered.

The loads on privacy screens are a lot larger than on regular glass balcony rails and will require stronger posts with bigger base plates.

Therefore the structural design of 1.8m high screens is governed by wind loading. For sites in the UK wind loading is calculated in accordance with British Standard 6399-2: 1997 Code of practice for wind loads. The basic wind speed for different geographical locations is obtained from Figure 6 of BS 6399-2. The basic wind speed varies from 20m/sec in an area around Oxford to 30m/sec in the North Scottish Islands.

The basic wind speed is adjusted by various factors to allow for differences in site conditions. These include the site altitude and topography, whether the site is in a town or in the country, distance from the sea, and height of the building.

In order to properly design a safe privacy screen there are some things to ascertain:

1)     The area the job is in in terms of basic wind speed. On each calculation there is a map of the UK with basic wind speeds.

2)     Altitude of site

3)     Effective height of the building

4)     Site distance from the sea.

The design must take into account the fixing method and structure being fitted to. Some areas in the UK are subject to gale force winds and the design must take these things well into account.

The first in a new series of advice from specialist suppliers is written by wood and beyond for BWP Architects:

Anyone who has recently fitted wood flooring will tell you that there’s more than meets the eye when it comes to options and styles. New technologies and advances in the way wood is sourced have contributed to an abundance of choice. In this blog post, we aim to explain your options so you are able to choose the best product for your precise circumstances.

Wood Flooring Types:

There are two common types of wood flooring and while for most properties your decision to fit one instead of the other won’t matter, in other cases it could prove a costly mistake. The most popular type is solid wood flooring. As you can gather by its name, each floor board is made from complete 100% solid wood. The second type is engineered wood flooring and while each floor board looks precisely like the solid type, they differ in their construction. Instead of complete wood, each floor board includes three or four layers of Plywood, MDF, Softwood and hardwood veneer on the top. Your decision to prefer one type to the other should be based on the particular characteristics of each technology.

Solid Wood Flooring – Because of their complete wood construction, they are regarded as the stronger of the two. Service life of a well-maintained floor could exceed 50 years. Each floor board can be sanded and stained after years of wear and tear thereby refreshing its look. Because of its natural construction, solid flooring has two common drawbacks. Floor boards are limited in size and the wood may experience a reaction to temperature changes. In some conditions the wood may expand (in hot conditions) or contract (in cold conditions), however if taken into account during fitting, it can be overcome.

Engineered Wood Flooring – Because of their contrasting construction, engineered are better suited for damp areas such as the kitchen or in properties that are located near a water source. While their service life may reach 50 years, the average service life is around 25 years. Floor boards are not limited in sizes and won’t react to temperature changes. However, sanding is not always possible and will depend on the thickness of the hardwood veneer. For most properties, be it residential or commercial, either type of wood flooring will suit. However, if in doubt you should consult with your architects.

Wood Flooring Grade:

The second consideration is the grade of the floor board. Contrary to common belief, grade is not an indication of quality, it is not an indication of durability and won’t affect the characteristics of the wood. It is in-fact an indication to how fine or how rustic the wood is. The more refine the wood is, the higher the grade is. The highest grade is ‘prime’ grade where the wood will feature minimal colour variation and minimal knots. The lowest grade is ‘rustic’ where you will immediately notice heavy grain markings, frequent colour variations and frequent knots of varying sizes. Other grades in between include select and natural. Your decision to prefer one grade over the other should be based your budget and your taste in wood.

Wood Flooring Finish:

The third consideration is the finish of the floor. Each floor board is covered in a transparent layer of coating which helps serves two important goals. In its original form, the finish is meant to provide the floor with basic protection from wear and tear, however in recent years it has been used to colour the floor in a colour different to the original colour of the wood. There are three practical coatings that you should consider.

Lacquer Based Finish – A layer that sits on the top of the wood, lacquer also serves as a waterproof coating. Useful for floor boards that are fitted in damp areas.

Oil Based Finish – A layer that sinks into the wood, oil is the easiest to repair by simply adding more oil. It is the common replacement to wax that has been used in the past.

UV Oil Based Finish – A layer that comes across as slightly glossy, thereby helping hide damage caused by wear and tear.

The Environment and Wood Flooring:

Wood flooring in most cases is sourced from sustainable forests where trees are replenished and ethically transported. If you come across a species of tree previously unknown or you wish to check their status, you can check the endangered list of trees online at www.iucnredlist.org. Supplier displaying the FSC mark which stands for ‘Forestry Stewardship Council’ www.fsc.org have been accredited for sourcing their woods from managed forests. Furthermore, it is in your right to ask the supplier as to the origin of their woods should you decide to check it. Most will have some sort of ethical statement.
