Architectural Design & Extension Plans in Andover

House extensions, loft conversions and building regulations drawings for homes in Andover and the surrounding Test Valley villages.

Andover · Hampshire

Orange Key designs house extensions, loft conversions and renovations in Andover and the villages of the northern Test Valley, preparing the planning and building regulations drawings needed for each project.

Homes in Andover

Andover grew substantially in the 1960s and 1970s, and many of the town's homes date from that expansion. These houses often have the plot space and roof form for rear and side extensions, garage conversions and loft conversions. The surrounding villages have older cottages and farm buildings that call for a more sensitive approach.

Planning permission in Andover

Planning applications in Andover are decided by Test Valley Borough Council. The historic town centre is a conservation area, and many villages to the north of the town lie within the North Wessex Downs National Landscape, where permitted development rights are more limited and design is looked at more closely.

Our services in Andover

For most homeowners in Andover, a project starts with house extension plans or loft conversion plans. Where a proposal needs consent we prepare the planning permission drawings and manage the application, and once it is approved we produce the building regulations drawings your builder and building control need.

We also design renovations, barn conversions and change-of-use projects, and prepare Land Registry lease plans for solicitors and landlords. If you are budgeting for a project, our house extension cost guide is a good place to start.

Common questions

Andover FAQs

What does Orange Key do in Andover?

We provide architectural design, house extension plans, loft conversion plans, planning permission drawings and building regulations drawings for homes in Andover and the surrounding villages.

Do I need planning permission for an extension in Andover?

Many single-storey rear extensions fall within permitted development, but larger and two-storey extensions usually need planning permission from Test Valley Borough Council, as do most extensions in conservation areas or the North Wessex Downs.

Can you convert my garage in Andover?

Garage conversions are common on Andover's estates. Some need planning permission, particularly where permitted development rights were removed when the estate was built, and all need building regulations approval.

How much do extension plans cost in Andover?

Fees depend on the size and complexity of the project and on whether planning permission is needed. We give a fixed quote once we understand the property and what you want to achieve.
