House Extensions in Wokingham

Usually, if that wall carries load. The size depends on the span, what sits above it, and whether a flat or pitched roof loads it. In some cases a proprietary lintel is sufficient, but the calculation is what decides that, not the appearance of the wall.

Yes. If the design work is done, we can pick up the structural calculations and the building regulations detail from the existing drawings, provided the drawings reflect what is actually on site.

It can. Across Wokingham the underlying ground is commonly London Clay with Thames river terrace gravels across the lower ground, and that has a bearing on foundation depth, on how a new bearing is detailed, and on how close to mature trees a foundation can sensibly go. That is a general description of the area rather than a statement about any particular plot, so where foundations are involved we design against what an investigation on the site actually shows.

Wokingham falls under Wokingham Borough Council. It is a unitary authority, so planning, building control and highways all sit with the same council rather than being split with a county tier. That matters because a set of calculations and drawings has to be submitted to the authority that actually covers the address, and on this patch the boundaries run close together, so neighbouring towns can sit with entirely different councils.

The Rose Street cottages are tightly terraced and often historic, so both party wall obligations and listed building consent can apply to the same project. If the property is semi detached or terraced, or if the foundations for any new element sit close to a boundary, the Party Wall etc. Act 1996 is likely to apply and notice has to be served before work starts. We can confirm the position once we have seen the property, and serve the notices as part of the same project rather than leaving you to arrange it separately.

Yes. The town centre conservation area covers Rose Street and much of the historic core, and several of the timber framed buildings are listed, which changes what can be altered internally as well as externally. Where any of that applies to a property, permitted development cannot be assumed, and on a listed building even internal alterations can need consent. We establish which of these apply to your address at the start, because it can change the structural solution as well as the paperwork.

The design and structural work is usually the quicker part. The variable is the approval route, since a full planning application runs to a statutory determination period while a permitted development scheme can move straight to building regulations.

Yes. Planning permission and building regulations are two separate systems. An extension that is entirely permitted development still needs building regulations approval, and that is where the structural calculations, insulation, ventilation and fire safety detail are assessed.

Yes. Alongside Wokingham we regularly work in Camberley, Bagshot and Lightwater, and across the wider Berkshire border area from our office in Fleet. Bear in mind that some of those neighbouring towns sit under a different council to Wokingham, so the planning and building control route can change from one to the next even over a short distance.

Yes. Wokingham is fully within our normal working area for house extensions, from Rose Street, Broad Street, Emmbrook and Woosehill through to the surrounding streets. Wokingham is a unitary authority, so planning and building control both sit with Wokingham Borough Council rather than being split with a county tier, which is a small but real difference from the Surrey side of our patch.
